This t tached to one end of the sewing machine arm,

and said actuating mechanism operatively connected with the vertically vibrating needle bar of the machine. Broadly, the present invention resides in the substitution for this operating connection with the needle bar of a power transmitting mechanism operatively mounted at the other end 1of the sewing machine arm and t including means whereby oscillatory motion is transmittedk to the vruliiing blade from the main shaft ofgthe machine at a selected speed ratio.

It is another object of the invention to pipi/ideA an improved mounting and arrangement `of the variable speed operating mechanism for'therufning blade upon the sewing machine arniso that there will be no interference with theconventional motor drive connection with the mainy shaftof the sewing machine and in which the several elements of said operating mechanism are compactly mounted andA arranged within a housing of comparatively small dimensions. n

`It is a further general object of theV present invention to provide such a variable speed oper-vv atingmeans for the oscillatory ruliling blade which is simple in construction, reliablefin its functional operation, Aand will not materially add to the production cost of the ruflling attachment as disclosedin my pending application.-

[With the above and other Vobjects-in view, the invention consists in the improved ruler operating mechanism, and in the form, construction and relative arrangeinentl of its several. parts v`as will yhereinafter be more fully described, illustrated in the accompanying drawings and subsequently incorporated in the subjoined claims.

In the drawings wherein I have shown one simple and practical embodiment ofthe invention, and in which similar reference characters designate corresponding several views: 1

Fig. 1 is a top planview of a-sewing machine`Vvl As claims. (o1. i12-134) Y l invention yrelates to rufflerjoperating mechanism and more particularly toY certain im` Y provements in ruiiiing attachments `for sewing of standard maltev showing a preferred embodi` ment of my present invention applied thereto.

Fig. 2 is an end elevation, the face plate of the housing for the ruffler actuating mechanism being removed.

Fig. 3 is an elevation of the opposite end of the sewing machine with the face plate for the housingof the variable speed operating mechanism removed, and t Fig. 4 is a horizontal sectional View taken substantially on the line 4-4 of Fig. 3.

"Referring in detail to the drawings, the conventional horizontally Vdisposed sewing machine arm is indicated at 5, said arm being integrally connected at one endwith the usual hollow standard orpedestal formed upon the base plate 6. The otherend of this arm is provided with the usual guide head 1 for the vertically vibrating needle bar 8 and the presser foot bar 9. The main shaft In is suitably mounted within the arm 5 and driven by the belt wheel I I, connected with the Voperating motor (not shown). The other end of the main shaft, is operativelyconnected with the needle bar 8 in a known manner to transmit vertical reciprocatingorv vibratory motionthereto. I

"For the purpose of this description, I have shown my present improvements as applied to a ruler actuating attachment similar to that shown in my pending application, but it will be understood as this description proceeds, that the novel features-of the present invention are not necessarily limited to a ruiiling attachment of this specic type. It will, therefore, suiiice to state that theactu'ating-means for the ruilling blade I3 is mounted within a suitable housing I4 attached to the end face lof the needle guide head 'I of the sewing machine arm and includes means for regulating the extent of throw of said blade. This actuating mechanism for the ruliling blade,

generally indicated at I5, is operatively connecty ed with one end of a rock shaft I6 which extends parallel with the arm 5 at the rear side vthereof and is mounted at one of its ends in a suitable bearing provided on lthe side wall of the housing I4. lThe lruiiling blade I3 is mounted for yielding pivotal movement on the lower end of an oscillatable arm II fixed at its upper end to a shaft I8 supportedv in the lower end of the housing I4 and with which the actuating mechanisml I5 is operatively connected. It will, therefore, be understood that in the rocking motion of the shaft I6 the mechanism-l5 transmits similarrocking motion to the shaft I8 whereby the arm II'and blade I3 are oscillated so that said the other end of said needle actuatingA shaft and having gear elements of relatively different diameters, and power transmission means connected with said rock shaft and comprising a radially adjustable element having a part adapted to be selectively engaged with means on the respective gear elements to transmit oscillating motion to said rock shaft at a selected predetermined speed.

4. In combination with a sewing machine having a main needle actuating shaft operatively connected at one end with the sewing machine needle, ruiiling mechanism mounted at said end of the needle actuating shaft including an oscillatory rufer blade and operating means thereforembodying a rock shaft, a gear train driven from the other end of said needle actuating shaft and having gear elements of relatively differentdi-f` ameters, an arm xed to the corresponding end of said rock shaft, and a member longitudinally slidable on said armhaving means adapted to be selectively connected with said different gear ele-l mentspto transmit oscillating motion to said rock shaft at a predetermined speed. I

5. In combinationA with a sewing machine having a main needle actuating shaft, rullling mechanism including an -oscillatory rufing blade and an operating shaft therefor, a plurality of power transmission elements operable at relatively different speeds and a driving connection between the same and said needle actuating shaft, and

means for operatively connecting a selected individual power transmission element with the blade operating shaft to actuate the latter at a predetermined speed relative to the needle actuating shaft. y

6. Inv combination Witha sewing machine having a verticallyv reciprocating needle, an oscillatory ruiiling blade mounted in operative relation to the lsewing machine needle and actuating means therefor including a rock shaft, 'an operating means for said rock shaft comprising a plurality of power driven transmission elements operable at relatively different speeds, and means for selectively connecting the individual power transmission elements with said rock shaft to actuate the latter at a predetermined speed.l

7. In combination with a sewing machine having a vertically reciprocating needle, an oscillatory ruling blade mounted in operative relation.

to they sewing machine needle and actuating means'therefor including a rock shaft, an operating means for said rock shaft comprising a plurality of power driven transmission elements operable at relatively different speeds, a member fixed to the rock shaft disposed radially'thereof,

and an element carried by said member, adjustable relative thereto and adapted to coact with means on a selected individual power transmission element to actuate the rock shaft vat a predetermined speed. f
